Carlos Castaneda was an Latin-American author.
Starting with The Teachings of Don Juan in 1968, Castaneda wrote a series of books that describe his training in shamanism, particularly with a group whose lineage descended from the Toltecs.
The books, narrated in the first person, relate his experiences under the tutelage of a man that Castaneda claimed was a Yaqui "Man of Knowledge" named don Juan Matus. His 12 books have sold more than 28 million copies in 17 languages.
Critics have suggested that they are works of fiction; supporters claim the books are either true or at least valuable works of philosophy.
